Description

[Detailed Description of the Invention] The present invention is useful when adjusting the position of a controlled object, etc.
This invention relates to a multi-directional switch used.

For example, when using a motor to remotely control a controlled object that requires attitude adjustment in two directions (left and right and up and down), such as the side mirrors of a car, two motors can be used in one.
Multi-way transfer switches are commonly used for operation by one switch. Traditionally, switches used for this purpose include those with a leaf spring contact attached to a spherical contact, and sliding switch types, but these all have complex structures. There were problems in that the number of parts was large, the assembly work was troublesome, and the cost was likely to be high.

The present invention has been made with the aim of solving these problems, and includes a movable contact made of a flexible material in which an inner movable contact and an outer movable contact surrounding the outer periphery of the inner movable contact are provided concentrically. By combining a contact plate and a fixed contact plate in which multiple sets of fixed contact groups consisting of inner fixed contacts and outer fixed contacts corresponding to each movable contact are arranged radially in the switching direction, each inner movable contact is fixed. By configuring the inner fixed contacts of each contact group to selectively contact the inner fixed contacts and the outer movable contacts to selectively contact the outer fixed contacts of each fixed contact group, it is possible to achieve highly reliable and low-cost multi-directional switching with a small number of parts. It provides a switch.

An embodiment in which the present invention is applied to a multi-directional switch for controlling the attitude of a side mirror will be described below. Fig. 1 is a plan view, Fig. 2 is a side sectional view, and Fig. 3 is an exploded perspective view.

Of course, each fixed contact group consists of an inner fixed contact (support) corresponding to the inner movable contact (property) of the movable contact root cause), and an outer fixed contact device corresponding to the outer movable contact (■), and both contact plates Qυ(2) are overlapped with the insulating spacer (C) interposed between them, and the inner movable contact (to) and the inner fixed contact (■) are connected at the inner notch (■) of the insulating spacer (C), and the outer notch (9) of the insulating spacer (C) ), the outer movable contact (2) and the outer fixed contact (2) are combined so as to face each other with a small gap in between. The fixed contact plate also serves as the bottom plate of the switch, and is attached to the switch case (1) with screws.
